Branded types in TypeScript enhance code readability, context, and type safety by providing an extra definition to existing types. They help in comparing entities with similar structures and filenames, improving code organization and clarity.
Working with branded types in TypeScript allows for a more organized way of validating entities, emphasizing specific variables, and ensuring validity throughout the code. This approach goes beyond using generic typed variables and enhances code maintainability.
Branded types are created in TypeScript by attaching a 'brand name' to the type, such as in the example of defining a branded type for an email address. There is no fixed syntax for creating branded types, and variables like '__brand' can be customized to suit the type.
